Ideastep KO1639 sports orthotic insoles feature a multi-layer EVA construction, medial, lateral, and transverse arch support, and a Poron XRD heel pad. Designed for sports and footwear applications, this model is intended for orthotic brands, footwear manufacturers, and wholesale distributors.
Its construction combines polyester fabric, blue EVA, orange split EVA, black perforated EVA, rigid orange EVA for arch support, and a Poron XRD heel pad. Custom color options and OEM/ODM services are available for businesses sourcing orthotic insoles for their product ranges.

Multi-Arch Support Structure
KO1639 incorporates medial, lateral, and transverse arch support within one insole design. This configuration provides a defined support structure for sports footwear and other footwear categories.
For product developers, the arch profile, material stiffness, layer arrangement, and overall thickness are key specifications to assess during product selection. These factors should be evaluated against the requirements of the intended footwear design.
Multi-Layer EVA Construction and Poron XRD Heel Pad
KO1639 combines several materials in a layered structure, with separate components for the upper surface, arch support, and heel area.
Polyester Fabric Top Layer
Polyester fabric forms the top surface of the insole. Its finish and compatibility with the underlying materials are relevant considerations when evaluating the product for a specific footwear range.
Blue EVA and Orange Split EVA
Blue EVA and orange split EVA form part of the layered construction. Their arrangement contributes to the overall insole structure. Material hardness, density, thickness, and layer placement should be confirmed against the final product specifications.
Black Perforated EVA
The black perforated EVA layer is a distinct component within the construction. Any claims about airflow or moisture management should be supported by relevant material data or test results.
Rigid Orange EVA Arch Support
The rigid orange EVA component forms the arch support structure. Its profile and stiffness are important specifications when assessing the insole for different footwear designs.
Poron XRD Heel Pad
A Poron XRD heel pad is positioned in the heel area as a dedicated cushioning component. Buyers should confirm the exact material specification and supporting test data before making specific claims about impact reduction or cushioning performance.
Applications Across Footwear Categories
KO1639 is intended for athletic footwear, boots, casual shoes, and dress shoes. This application range gives footwear manufacturers and distributors a model to evaluate across different product categories.
Suitability depends on the finished insole dimensions, thickness, arch profile, and the internal construction of the target footwear. These specifications should be confirmed before the product is incorporated into a footwear design or sourcing plan.
